New species of ostracods from the non-marine upper Barremian (Lower Cretaceous) of Vadillos-1 (Cuenca, Spain)

The upper Barremian (Lower Cretaceous) palaeontological site of Vadillos-1 is located in the northern part of the province of Cuenca, Spain. It comprises a sedimentary sequence in Wealden-type facies, rich in non-marine ostracods. In these materials, species of Cypridea have been identified, in part...

Descripción
Sumario:The upper Barremian (Lower Cretaceous) palaeontological site of Vadillos-1 is located in the northern part of the province of Cuenca, Spain. It comprises a sedimentary sequence in Wealden-type facies, rich in non-marine ostracods. In these materials, species of Cypridea have been identified, in particular Cypridea isasae, characterized by its rounded cyathus, and Cypridea ventriosa, being distinguished by the subcircular outline and a large rostrum separated by a very marked alveolar notch. Additionally, numerous specimens of Cypridea vatra nov. sp., defined by its well-marked anterior cardinal angle, and Cypridea marihoni nov. sp., well defined by its ornamented carapace, have been described. Other specimens have been assigned to the genus Cyclocypris, specifically to Cyclocypris bamba nov. sp., characterized by its inflated carapace and piriform outline. These taxa are reported for the first time in the study area and are characteristic of alluvial and palustrine palaeoenvironments. This analysis provides the basis for future studies that will allow a more precise interpretation of non-marine Barremian palaeoenvironments.
